| Text and mathtext using pyplot | |
| ============================== | |
| Set the special text objects `~.pyplot.title`, `~.pyplot.xlabel`, and | |
| `~.pyplot.ylabel` through the dedicated pyplot functions. Additional text | |
| objects can be placed in the axes using `~.pyplot.text`. | |
| You can use TeX-like mathematical typesetting in all texts; see also | |
| :ref:`mathtext`. | |
